-# asciigoat's INI parser
-
-[![Go Reference][godoc-badge]][godoc]
-[![Go Report Card][goreport-badge]][goreport]
-
-`asciigoat.org/ini` is a simple Go library that very loosly parses
-[`INI`-style][wikipedia-dosini] documents allowing the implementation
-of stricter parsers of similar form.
-
-**asciigoat** is [MIT](https://opensource.org/license/mit/) licensed.

-
-## Parser
-
-[`parser.Parser`][godoc-parser-parser] uses
-[`asciigoat`'s lexer][godoc-lexer] to process an `INI`-style document
-emiting tokens and errors via callbacks.
-
-## Other Implementations
-
-Other implementations exist, and they are mature and feature-rich, but they
-are highly opinionated about what's a valid file. Built around maps they don't
-allow repeating names and constraint what characters can be used.
-
-These are great when you can adapt, or already agree, to their conditions but
-that's not always the case when you are parsing configuration files from
-other applications and that's what [asciigoat.org/ini][godoc] attempts to solve.
